This Lady Wants $1 Million a Month in Child Support

We don't know who this woman is, but clearly isn't... from this planet.

A multibillionaire hedge fund owner could be on the hook for nearly $1 million a month in child support -– including staggering sums for a private jet, vacations and stationery -– according to newly filed court documents in an Illinois case that threatens to be one of the biggest divorce settlements in the country. Ken Griffin filed for divorce last year from his wife Anne after 11 years of marriage, citing irreconcilable differences. The couple is the parents of three children, ages 2, 4 and 7. In those court filings, Ken Griffin says his estranged wife reported how much it costs to raise their children each month, including $14,000 for food, $300,000 for a private jet, $160,000 for vacations and $2,000 for stationery. [Plus: $8,000 for gifts, $60,000 for a private staff. And she wanted $450,000 for a St. Bart's vacation over winter break.] According to Illinois law, children of divorce are entitled to continue the lifestyle they enjoyed during the marriage. A spokesperson for Dias Griffin told ABC News that her husband is trying to avoid his financial responsibilities to his family. But Griffin said in court papers that he already pays for virtually “every expense related to the children,” and that his estranged wife simply wants him to "continue funding her lifestyle." The marriage included five homes, access to two private airplanes, a household staff and 24/7 security services for the children. Dias Griffin is also asking a judge to throw out her prenuptial agreement, which she says entitles her to only 1 percent of her husband’s estimated $5 billion estate -– or around $50 million. She says she signed the document under duress the day before the couple's 2003 wedding in Chicago. Griffin is the founder of the Chicago-based Citadel LLC.
